Universal garment pocket and method

ABSTRACT

A MACHINE STITCHED, FLAT COMPLETELY TAILORED AND FINISHED UNIVERSAL POCKET IS ATTACHED WHILE BEING CONSTRUCTED, TO ANY TYPE OF, AND AT ANY POINT OF, AN UNLINED GARMENT IN WHICH POCKETS ARE VISIBLE, SUCH AS TROUSERS, UNLINED COATS, SKIRTS AND THE LIKE. IT IS REVERSIBLE FOR OUTSIDE ARRANGEMENT AND VISIBILITY. THE POCKET BAG RECEIVES A GUSSET FOR EXPANSIBILITY. IT IS SECURED TO THE GARMENT ONLY AT THE SLIT OR ENTRANCE OPENING OF THE POCKET BY A SINGLE CONTINUOUS LINE OF MACHINE STITCHING. THE POCKET SHEET IS FOLDED IN HALF WITH THE FOLD AS CLOSELY ADACENT THE SLIT AS THE STITCHING PERMITS. THE SLIT IS A STRAIGHT, CURVED, CROOKED OR BENT LINE. THE CORRESPONDING END PORTIONS OF THE STITCHING ON OPPOSITE SIDES OF, AND CIRCUMSCRIBING, THE SLIT CONVERGE TO MEET AT A RELATIVELY OR SLIGHTLY DULL POINT. DURING CONSTRUCTION, THE POCKET SHEET OR FINISHED POCKET BAG IS TURNED BACK AND FORTH THROUGH THE SLIT AS MANY TIMES AS REQUIRED TO GIVE COMPLETE ACCESS FOR CONTINUOUS MACHINE STITCHING OF ALL PARTS, SUCH TURNING BEING POSSIBLE BECAUSE OF THE INDEPENDENCE OF THE POCKET BAG OR SHEET FROM THE GARMENT EXCEPT FOR THE SLIT STITCHING. EMBELLISHMENT SUCH AS FACINGS, FLAPS, TAPES, ZIPPERS, STRIPES AND THE LIKE ARE APPLIED DURING CONSTRUCTION.

No. 797,525Int. Cl. A41d 27/20 US. Cl. 2-247 18 Claims ABSTRACT OF THE DISCLOSURE Amachine stitched, fiat completely tailored and finished universal pocketis attached while being constructed, to any type of, and at any pointof, an unlined garment in which pockets are visible, such as trousers,unlined coats, skirts and the like. It is reversible for outsidearrangement and visibility. The pocket bag receives a gusset forexpansibility. It is secured to the garment only at the slit or entranceopening of the pocket by a single continuous line of machine stitching.The pocket sheet is folded in half with the fold as closely adjacent theslit as the stitching permits. The slit is a straight, curved, crookedor bent line. The corresponding end portions of the stitching onopposite sides of, and circumscribing, the slit converge to meet at arelatively or slightly dull point. During construction, the pocket sheetor finished pocket bag is turned back and forth through the slit as manytimes as required to give complete access for continuous machinestitching of all parts, such turning being possible because of theindependence of the pocket bag or sheet from the garment except for theslit stitching. Embellishment such as facings, flaps, tapes, zippers,stripes and the like are applied during construction.

This invention relates to garment pockets and the methd of making themand particularly to machine stitched pockets for unlined garments.

THE PROBLEMS Difficulties have heretofore been experienced in making andinstalling pockets in garments in such a manner that all stitching inthe pocket can be made by machine for quantity production while avoidingdefects in the tailoring of the pocket. Especially in the side pocketsof trousers have such difficulties been peculiarly unavoidable. The sideseam of the trousers interferes with the pocket bag therebynecessitating cutting of the bag to permit the flaps of the seam toemerge from the pocket, or in another form of construction necessitatestwisting of. the seam flaps so that they cannot be busted that is, madeto lie fiat.

In lined garments such as jackets, coats and the like, raw edges andpoor tailoring of breast and side pockets are hidden by lining eventhough many would prefer elimination of the lining. In unlined garments,raw edges and poor tailoring are often hidden by tape.

The side and hip pockets of trousers have heretofore customarily beenanchored in the waistband of the trousers necessitating the use ofexcess pocket material and labor in the operation. Furthermore, byreason of the straight line stitching along opposite sides of the slitwhich forms the pocket entrance, unwanted material near the ends of theslit is frequently cut so that it may be bent back out of the way of theopening at those points. This results in a multiplicity of thickness ofobjectionable material formed by the welts or folds and difiicult tohold properly in place without fraying especially when fre quentlystressed, causing bunching, creasing, wrinkling or lumping at thosepoints. Pressing the garment at the lumps frequently results in anunsightly shine on the face of the garment.

Nor is continuous machine stitching of the bag-closing seam possiblewith trouser pockets as heretofore constructed which are anchored at thewaistband.

THE SOLUTION The difficulties mentioned have been resolved by thepresent invention which permits the construction and installation of apocket at any point of any type of garment using continuous oruninterrupted lines of machine stitching and a straight pocket openingslit or a slit which is not straight and may even be sinuous.

In brief, the sheet forming the pocket bag is first securedapproximately at the middle line thereof to the garment and facingsheets by a single continuous line of stitching circumscribing the slitof whatever shape the slit may be. The corresponding end portions of thestitching on the opposite sides of the slit converge to meet at arelatively sharp or slightly dull point. Secondly, after the flaps,facing, stripes, or the like having been stitched into place the pocketsheet is passed through the slit, folded exactly in half along a foldline adjacent the slit to bring the edges of the folded sheet intoregistration with each other and the folded sheet flattened so that thebag-closing continuous stitch can easily be made thereby finishing thepocket bag. Thirdly, the stitched finished bag is then turned backthrough the slit to complete the installation.

It will be understood that the thicknesses of the various fabric sheetsshown in the drawings have been greatly exaggerated for clarity ofillustration.

Referring to that form of the invention shown in FIGS. l-3 as applied tothe side pocket of a pair of trousers, the front garment panel 25 issecured by the preliminary side seam forming stitching 26 to the rearpanel 27 throughout the lengths of the panels in advance of theattachment of the pocket to the garment. Said stitching extends pastboth ends of the pocket entrance opening 28 and forms the seam flaps 25aand 27a. Since the pocket is made the same way as for those located atother parts of the trousers or other garments, the steps and structureshown in FIGS. 5-11 apply equally as well to the pocket of FIGS. l-4.Reference will therefore be made to FIGS. 5-11 to explain the sidetrouser pocket of FIGS. l-4.

The slit 28 forming the entrance opening is made only after thepreliminary assembly of the pocket sheet 29 which is arranged on therear face of the garment sheet or panels, with the facing sheet 30, 30aarranged on the front face of the garment sheet as shown in FIG. 6. Thesheets are suitably marked to permit them to be arranged in their properrelation with respect to each other and to the pocket slit or opening 28in a manner which is well understood. The sheet forming the pocket wallsis integral or initially closed along, and is symmetrical about, thecenter line of the sheet at which the fold of the pocket sheet islocated. The sheet may be of a single piece of material or of severalpieces. In either case, no additional pocket-closing stitching isrequired at said center line or fold to join the two folded walls of thepocket bag together since the two walls are either continuous or arejoined in advance of the assembly of the parts. The fold of the pocketsheet extends in the general direction of, and preferably as close aspossible to, the slit or entrance opening.

All the sheets are stitched together in their flat condition by thestitching 33 with that part of the garment sheet at the slit sandwichedbetween the facing sheet 30 on the front or right face 31 of the garmentsheet and the pocket sheet 29 on the rear or wrong face 32 thereof. Inthe case of the side pocket, the pocket sheet is arranged with itscenter line as nearly as possible coincident with the seam stitching 26,the pocket sheet being against the seam flaps 25a and 27a. Thecontinuous single line of stitching 33 of generally elliptical shape ismade by machine to encompass or surround the slit. The end portions 34,35 of the substantially parallel coextensive and similar sides 36, 37 ofthe stitching 33 on opposite sides of the slit, converge to meet at therelatively sharp points 38 as best seen in FIG. 4

The slit 28 is then made through all of the sheets. In the case of theside pocket, the slit may pass through a panel flap as well as through apanel, but it may just sever the stitching 26 without cutting thegarment material. The slit passes through the garment sheet 40 of FIG. 6and through the pocket sheet 29 about half way between the opposedstitch sides 36 and 37. Said sides of the stitching 33 are spaced awayfrom the slit a minimum distance just sufficient to prevent ravelling ofthe cut edges of the fabrics resulting from the slit. For the samereason, the slit ends as close as possible to the intersection point 38of the stitch sides that is, where the stitching changes directionabruptly.

The facing sheet is long enoughto extend slightly past the end points 38of the stitching and wide enough to line the face of the pocket sheet inthe usual manner. After the sheets have been stitched together andslitted, the facing sheet 30, 30a is completely turned through the sliton to the rear face of the pocket sheet as shown in FIGS. 2 and 7,carrying the narrow edge portions thereof secured by the stitch 33 withit, to turn it together with the turned edge portions between the foldand the facing sheet and to conceal said portions between the facingsheet and the pocket sheet. Said facing sheet is then fiattened on tothe rear face of the pocket sheet and tensioned slightly if necessary toeliminate any slight wrinkles or creases which may develop at the stitchvertices 38 of the slit as the result of turning the facing sheetthrough the slit. Such flattening is possible because of the convergingend portions 34, 35 of the stitching, little or no surplus materialremaining at the corners to interfere with the flattening step. Thefacing sheet is also adjusted transversely to arrange the turned bend 41of the garment sheet on one side of the slit in a position to overhangslightly the adjacent turn 42 on the facing sheet as is re quired forgood tailoring (FIGS. 2 and 3).

The facing sheet 30, 30a having been flattened and adjusted, one partthereof on one side of the slit 28 is stitched to the rear pocket wall43 and on the remaining part 30a on the other side of the slit isstitched to the opposite pocket wall 44, the sheets now being in theposition of FIGS. 2 and 7, for easy access thereto. The garment panelsor sheet may readily be turned out of the way for this purpose. Suitablebar tacks 55 are made at the ends of the slit if desired, after theparts of the facing shelet have been stitched down to line therespective pocket wa s.

Where, as in the side pocket of FIGS. 2 and 3, a simulated welt isrequired at the front lip of the pocket mouth or slit, the welt stitch45 is made through the facing part 30a and through all of the othersheets. The pocket walls are now ready for closing into a bag. It hasbeen indicated that the pocket sheet may be a single continuous sheet ora stitched together composite sheet so long as the two walls of thepocket when folded, coincide at the edges thereof. The line of fold mayeven be a line of stitching joining the pocket walls adjacent the slit.

In order to turn in and conceal the raw edges of the pocket walls, theyare turned through the slit from the positions of FIG. 2 or 7 toward thedash-dot line positions shown in FIG. 2 and as is indicated by thearrowed direction lines 46 of FIG. 2. The converging end portions 34, 35of the stitching 33 aid materially in making such turning practical andeffective without the need for cutting, notching, bending or otherwisedisposing of unwanted material which tends to make lumps, wrinkles,creases or the like, and results in poor tailoring. The arrangement ofthe center line of the pocket sheet at the slit is also of considerableassistance in permitting turning of the pocket inside out back and forththrough the slit.

In FIG. 8, only parts of the pocket wall parts of the facing sheet havebeen shown as passed through the slit for the purpose of clarity and foreasy comparison with the positions of the parts in FIG. 7. The positionsin which the parts become arranged for easy access to the pocket wallsby the sewing machine, are shown in FIGS. 9 and 9a. The pocket wallshave been swung together, the wall 44 moving downwardly in the directionof the arrow 48 of FIG. 8 to a substantially horizontal position and thewall 43 swung upwardly in the direction of the arrow 49. The uppergarment part is swung downwardly in the direction of the arrow 50 andthe lower garment part swung upwardly in the direction of the arrow 51.

The peripheral edges of the pocket walls are now brought intoregistration with each other and to coincide thereby forming the centralfold 52, this being possible because the pocket sheet is symmericalabout its center line, regardless of the shape selected for the pocketbag. To prepare for the bag-closing stitching, the rear pocket wall ofFIG. 2 is swung in the direction of the arrow 53. The continuous line ofmachine stitching 47 securing together the peripheral portions of thepocket walls all around, except at the fold, is now made to close thebag completely except at the pocket entrance, and to suspend the pocketfrom the garment only by the line 33 of stitching except for theoptional bar tacks 55 (FIGS. 1 and 11) close to the ends of the slit.

Obviously, additional strength or reinforcement may be supplied when thepocket is finally positioned irreversibly by attachment to the garmentsheet at additional points, though such additional attachment is usuallyunnecessary. Reinforcement of the pocket in the usual manner may also bedone. The final step, in making the pocket of FIGS. 1 and 11 is in theturning of the closed and finished pocket bag through the slit and fromthe inside out position in the direction of the arrows 56 of FIG. 2 intothe right side out position of FIG. 3, or from the inside out positionof FIG .9 into the final position of FIG. 10, along the arrows 60, anddown. The garment parts are also moved from the horizontal to thevertical in the directions of the arrows 62 and 63 as will now bereadily understood.

That the slit forming the entrance opening of the pocket may take shapesother than straight and that the pocket sheet may also vary in shape isillustrated in FIGS. 12-14. In FIG. 12, the slit 65 is L-shaped, but theend portions of the surrounding stitching converge at 34, 35 in the samemanner as in any of the other forms of the pocket assembly. A sort ofhalf flap 66 is thereby created. The fold line 52 for this pocket isshown for illustration only as considerably above the slit, but it maybe as close to the long sides of the stitching as is convenient.

In FIG. 13 showing a U-shaped slit 68, the resulting flap 69 hingesabout the line 70 indicated as joining the ends of the slit. The pocketfold at 71 may also be close to the hinge line 70.

The slit 72 of FIG. 14 is of sinuous shape, the resulting double flap73, 74 comprising a number of similar fingers in each flap.

Enough has been said to make it clear that the slit and the pocket maytake a. variety of shapes. The versatility of the universal pockethereof will also be clear when it is seen that the pocket sheet andfacing sheet can be manipulated by turning back and forth through thepocket opening as many times as is desired without interference orhinderance and that the sheets, including the garment sheet, or easilyarranged to take a separate flap, or a zipper, or stripes or otherconventional pocket parts or embellishments in a well known manner whichneeds no further illustration or description.

In FIG. 15 is shown the gusset 75 connecting the walls 76, 77 of thepocket around the periphery thereof by means of the stitching 78, 79.The Walls are conveniently of separate pieces of pocket material and thegusset is connected thereto when the bag is finally closed.

The adaptation of the pocket to one which may be arranged in anoperative position either at the rear of the garment or at the frontwith little change in its construction to make it completely reversible,will now be explained. Such pocket is shown in FIGS. 16-l8 in itsreversed or outside position and in FIGS. l92l in it inside or normalposition. This pocket differs from those above described by reason ofthe second slit 80 in the rear wall 81 of the pocket sheet and thetailored finishing of said second slit. The raw edges resulting fromcutting said second slit are turned in and covered by the coveringmember '82 at the upper edge of the slit and by the folded covering orextension member 83 enclosing the lower edge of the slit. The member 82together with that portion of the pocket wall to which it is attached,form a flap having a button hole 87 therein optionally receiving thebutton 84 on the lower covering member -83. Said members 82 and 83overlap sufiiciently to permit the member 82 to serve as a flap and todetachably cover the second slit when desired. A short vertical cut 85(FIG. 19) at both sides of the flap permits swinging of the flap intoand out of the pocket.

When the pocket is in the reversed position of FIGS. 16-18 and theexposed pocket is in use, the flap 82 may be moved to the inside of thepocket and buttoned on to the button 86 on the pocket wall 43. When thepocket is in the inside or normal position of FIGS. 19-21, the flap isalso inside of the pocket and is buttoned to the button 84 therebyclosing off the pocket opening 80 and leaving the pocket opening 28accessible as in the other forms of the pocket.

It will now be seen that there has hereby been provided a universalpocket and method of making it meeting the objections and remedying thedefects of garment pockets heretofore in general use; that the pocket ismachine stitched throughout with resulting economy of material andlabor; that it may take a variety entrance opening and pocket outlineforms; that it can be turned back and forth as necessary for completeaccessibility and reversal; that it is finished with high qualitytailoring; that it accommodates itself to conventional appearance.Welts, facings and embellishments; that it is independent of waistbands,side seams and of the garment sheet except at the pocket entranceopening and consequently, that the objects of the invention areadequately attained in an efficient and practical manner.
